17” American Racing Torque Thrust Wheels

If it was me, I would do a 17x8 minimum with a 245/45 tire on the front. Since the offset looks to be custom, if you are (or plan to) run stock brakes, a +24mm offset should work. This is effectively what I have on the front of my Duster and didn't have to do a thing to the fenders. If you want a bigger tire, like a 275/35, you will need to go to an 18" wheel with more offset and tweak the front lower opening.

The back (in my opinion) requires a 275+ tire to proportionally fit the car. I would suggest taking some measurements and see where your current tire sits and figure out the difference. This is a nice webite to help you - Tire Size Comparison

If you run an aftermarket front brake kit, the offset will probably need to increase depending on the kit.

Watch for hub sizing issues, or issues where the wheel has the right spec but the hub tapers and won't fit over the hub snout.
